Bose system with an aftermarket HU
« on: 18 April 2010, 19:56:24 »

Hi, first technical post, please be gentle. I am getting an Omega Elite with the Bose system and have seen a few posts saying that the headunit cant be changed because it needs line outputs.

Could this solve the problem?

No, although the BOSE amp is using line level inputs, the actual voltages are unique to the BOSE system, and nothing aftermarket will run correctly with it.

To make matters worse, the BOSE speakers in the car are 2 Ohms impedance instead of the more conventional 4 Ohms ones, so must also be replaced if running anything aftermarket

One thing to bear in mind is that the Bose loom is still useful if your ok with a soldering iron as it takes a remote switch on, 12V, 0V, line out and speaker feeds from front to rear / rear to front.

Can save you a bit of time but needs some tweaking at the HU and Amp ends for the correct connectors. I think the +12V is about 20A so make sure the Amp doesn't require too much power.

Some cassette adapters are poor, even supposedly 'quality' ones.  Yet I have a real cheap, nasty one, must be 10-15yrs old, and its superb (for my tone deaf ears). Trouble is, I dont have a cassette player ;D - which pleased Mrs TheBoy, as she's now nicked it for her car ;D

Remember NEVER to use one of the tape adaptors on a electronically assisted cassette loading mechanism, as it can cause severe stress to the mechanics due to the fly lead causing an obstruction.

If you have the older style cassette deck that need to to depress a button to manually and mechanically eject the tape, then you should be fine with these.

The (naff) R770 in her Rover is mechanical. Seem to recall the CCR600 and CCRT700 are as well.

But the el-cheapo cassette adapter worked a treat in my trusty old 18yr old Kenwood, that is most definately soft touch.  I love that headunit, shame the '2' button has dropped off now (but it is really old)

I`m not saying the adaptors don`t work, far from it, but when you come to eject the tape, if it jams, as they often do, a mechanical one will require so much force that you will stop pressing the button and have a look at it, whereas the electronic ones will keep trying until the gears have stripped on the loading mech.

Ah, getcha :y

My cheapo - the best I've ever used :o - the wire comes out on the corner of the top and the side you see when inserted, so it only really goes in one way, and only in decks where the heads are on right (I think, from memory). Never had it get caught :)

Hi Guys. Just sharing that I've actually upgraded my stock HU (CCR 2006) to a Kenwood (IPOD and USB ready) 2din and it works very well with the Bose Amp and Speakers.  It was just a straightforward swap with with you still being able to control the balance (L-R) and fade (F-R) of the speakers. The drawback is that you still can't control the bose subs from the HU as the Bose system is an integrated Front Channel, Rear Channel and Sub Channel. Hope this helps
